Hi guys thanks for taking a look.
i want to drive a relay via a transistor operated by arduino pin. this is what i've come up with
ive put the arduino pin on a 5 second blink but but i am having no switching thru the transistor, in fact there seems to be a bypass right upto
the relay. I havnt implemented the relay yet just thought id test the transistor first and when i measured after R1 im getting 11.78v steady.
I've checked the Arduino output and thats doing what it should.
any suggestions??
